Abstract

An optical path folding element includes an incident surface, a path folding surface and an exit surface. The incident surface allows a light ray to pass into the optical path folding element. The path folding surface folds the light ray from the incident surface. The exit surface allows the light ray to pass through and depart from the optical path folding element. One of the incident surface and the exit surface includes an optical effective portion and at least one engaging structure. The engaging structure can be symmetrically disposed around the optical effective portion and includes an annular surface portion and an inclined surface portion. The annular surface portion surrounds the optical effective portion, and the inclined surface portion is located between the annular surface portion and the optical effective portion. When the specific condition of an angle between the annular surface portion and the inclined surface portion is satisfied, both of the engaging effect and the alignment effect of an imaging lens module using the abovementioned optical path folding element can be achieved.
